Two cross-sectional studies investigated media influences on adolescents’ substance use and intentions to use substances in the context of exposure to parental and peer risk and protective factors. A total of 729 middle school students (n = 351, 59% female in Study 1; n = 378, 43% female in Study 2) completed self-report questionnaires. The sample in Study 1 was primarily African-American (52%) and the sample in Study 2 was primarily Caucasian (63%). Across the two studies, blocks of media-related cognitions made unique contributions to the prediction of adolescents’ current substance use and intentions to use substances in the future above and beyond self-reported peer and parental influences. Specifically, identification with and perceived similarity to media messages were positively associated with adolescents’ current substance use and intentions to use substances in the future, and critical thinking about media messages and media message deconstruction skills were negatively associated with adolescents’ intention to use substances in the future. Further, peer influence variables (e.g., peer pressure, social norms, peer substance use) acted as risk factors, and for the most part, parental influence variables (e.g., parental pressure to not use, perceived parental reaction) acted as protective factors. These findings highlight the importance of developing an increased understanding of the role of media messages and media literacy education in the prevention of substance use behaviors in adolescence.  相似文献

The current study examined concurrent and longitudinal predictors of early adolescents’ involvement in Internet aggression. Cross-sectional results (N = 330; 57% female) showed that the likelihood of reporting Internet aggression was higher among youth who spent more time using Internet-based technologies to communicate with friends and who were themselves targets of Internet aggression. Offline relational aggression and beliefs supportive of relational and physical aggression also predicted concurrent involvement in Internet aggression. We used longitudinal data (N = 150; 51% female) to distinguish between youth who were aggressive in traditional contexts only (i.e., school) from those who were aggressive both online and offline. These results indicated that youth who were aggressive both online and offline were older at the initial assessment, were targets of Internet aggression, and held beliefs more supportive of relational aggression than youth who were aggressive offline only. Implications and directions for future research are discussed.  相似文献

Social cognitive models examining academic and career outcomes emphasize constructs such as attitude, interest, and self-efficacy as key factors affecting students’ pursuit of STEM (science, technology, engineering and math) courses and careers. The current research examines another under-researched component of social cognitive models: social support, and the relationship between this component and attitude and self-efficacy in math and science. A large cross-sectional design was used gathering data from 1,552 participants in four adolescent school settings from 5th grade to early college (41 % female, 80 % white). Students completed measures of perceived social support from parents, teachers and friends as well as their perceived ability and attitudes toward math and science. Fifth grade and college students reported higher levels of support from teachers and friends when compared to students at other grade levels. In addition, students who perceived greater social support for math and science from parents, teachers, and friends reported better attitudes and had higher perceptions of their abilities in math and science. Lastly, structural equation modeling revealed that social support had both a direct effect on math and science perceived abilities and an indirect effect mediated through math and science attitudes. Findings suggest that students who perceive greater social support for math and science from parents, teachers, and friends have more positive attitudes toward math and science and a higher sense of their own competence in these subjects.  相似文献

The aim of the present study was to examine a model positing that association with deviant peers mediates the relation between adolescent perceived parenting behaviors (maternal monitoring and involvement), the interaction of these parenting behaviors, and delinquency in a sample of 135 urban African American adolescents (13–19 years of age). Regression analyses revealed a monitoring by involvement interaction among African American females, suggesting that maternal monitoring may effectively reduce delinquency among African American female adolescents, and that this reduction may be enhanced by increased maternal involvement. Among African American males, only the relation between association with deviant peers and delinquency was supported, suggesting that maternal parenting behaviors may, in isolation, be insufficient in the prevention of delinquent behaviors in African American male adolescents. The results suggest that the pathways from parenting to association with deviant peers and delinquency may differ in males and females, and the salience of certain parenting behaviors may differ across gender.

This study examined the construct validity of antisocial personality disorder (ASPD) diagnosed in adolescence. Boys and girls were grouped by history of DSM-III-R conduct disorder (CD) and ASPD: Controls (n=340) had neither diagnosis; CD Only (n=77) had CD by age 17 but no ASPD through age 20; Adolescent ASPD (n = 64) had ASPD by age 17. The Adolescent ASPD group was then compared to 20 young adult men who met criteria for ASPD (ASPD group). As expected, the Adolescent ASPD group had significantly more depression and substance use disorders, a greater performance>verbal IQ discrepancy, more deviant peers, and poorer academic functioning than the CD Only group and Controls. The Adolescent ASPD and ASPD groups did not differ on most variables. Results support the construct validity of Adolescent ASPD and suggest that such a diagnosis could help identify adolescents at risk for persistent antisocial behavior.

The fashion for ‘subaltern studies’ has taken researchers back to the archive and field in search of social agents both marginalised and forgotten. In Mexico this has entailed an exacting task of reconstructing the lives of Indians and peasants on the remote frontiers of state influence. The books reviewed here are worthy examples of this project. They offer illuminating glimpses of the ways in which such semi‐autonomous societies experienced the extension of state rule as modern Mexico emerged painfully as a nation. If they are to be faulted it is in the emphasis they place on ‘the People's’ resistance to assimilation, implicitly heroic, whilst casting a rather contemporary light, often explicitly pejorative, on to the efforts of those other agents whose efforts were directed at the creation of a uniform citizenship.

Morality, competence, and sociability have been conceptualized as fundamental dimensions on which individuals ground their evaluation of themselves and of other people and groups. In this study, we examined the interplay between self-perceived morality, competence, and sociability and relationship quality within the core social contexts with which adolescents have extensive daily interactions (family, friends, and school). Participants were 916 (51.4% girls; Mage?=?15.64 years) adolescents involved in a three-wave longitudinal study with annual assessments. The results of cross-lagged analyses indicated that (a) self-perceived morality was more important than self-perceived competence and sociability in strengthening family, friend, and school relationships; and (b) high-quality friendships led to increasing levels of self-perceived morality over time. Overall, this evidence advances our theoretical understanding of the primacy of morality from a self-perspective approach and highlights the developmental importance of friends.  相似文献
